Does this mean that I need to install all of this? (PySide2, PyQt5, PySide, PyQt4, wxPython, GTK, or fltk).

I tried using matlab and it run successfully after I installed the Image processing Toolbox. Could you please tell me how to use my own image? Do i just replace the images into the input_folder?

from vrn.

Yeah put your images in the input folder and they should process. Glad you got it working.

from vrn.

By the way - the matlab surface extraction function is better than what I could find in python anyway, so the quality should be better :-)

Thanks for your help! I tried with my own image and it's working good.
